BOW

GUN.

Application filed February 8, 1926. Serial No. 86,727.

My invention relates to bow-guns, and, it is a distinct and practical improvement to overcome certain practical objections to, and defects in, the present types ofbow-guns.

The object of my present invention is to provide a bow-gun of high effic ency, power and general utility-for which such a device can be used, as for instance by police departments to shoot tear, or gas bombs to disperse a mob, by fire departments in shooting a prepared ball of twine to provide connecting means of rescue to occupants of high buildings out of reach of ladders, or shut off from fire escapes and by individuals interested in archery as a popular outdoor or indoor sport, amusement and exercise.

A further object of the invention is to.

provide a bow-gun which possesses advantages in points of simplicity and efficiency,

and, at the same time proves itself comparatively inexpensive in manufacture.

With the above and other objects in view, the invention consists in the novel features of construction, arrangement and combination of parts hereinafter more fully described and finally pointed out in the claims hereto appended.

Referring to the accompanying drawings forming a part of this specification, wherein like characters of reference denote similar parts throughout the several views:

Fig. 1 is a side elevation of the wooden bow member.

' Fig. 2 is a plan view of the ribbed metallic reinforcing strip which is applied to the I wooden bow member.

Fig. 3 is a side elevation of a bow-gun embodying the features of my invention.

Fig. 4 is a sectional view taken on line 44 of Fig. 3.

Fig. 5 is a detail of the rear end of the guide member.

Fig. 6 is a front elevation of the slidable cross head mounted upon the aforesaid guide member.

Fig. 7 is an end elevation of the bow gun.

- Fig. 8 is arfront elevation of the arrow rest and guide plate as attached to the bow.

Fig-=9 is a modified form of how gun.

Inciififying out the aim of my present invention, I employ" a suitable resihent wooden bow member 1 of any desired shape and size, preferably tapering towards its ends an having its ends suitably and permanent- 1y .bent or curved forwardly, as at 2, as s own in Fig. 1.

A suitable resilient metallic facing strip 3 is suitably fixed to the forward face of the wooden bow member 1. This strip is provided with a pair of opposed and aligned longitudinally directed ribs 4 which are pressed outwardly in the strip and gradually tapered to a point at their outer ends, as clearly shown in Fig. 2. The extremities of the resilient facing strip 3 are bifurcated to provide the end loops 5 to pivotally receive the arms 6 of the wire loop connections 7.

A second resilient facing strip 8 may, or may not be used as desired, and when used, it is suitably fixed to the rear face of the wooden bow member 1. This strip 8 is also rovided with a pair of spaced and aligned ongitudinally directed ribs 9 which are pressed outwardly in the strips and gradually tapered to a point at their outer ends.

A very powerful bow-gun of predetermined strength preferably employs both facing strips 3 and 8 wherein a lighter, cheaper and weaker bow-gun will employ but one of the facing strips, as is manifest. A su table thumb guard member 10 provided with the loops 11 is suitably fixed to the rear face of the bow-gun member 1 midway. the ends thereof, as shown in Fig. 3. The thumb guard member 10 is provided with an opening 12 which registers with an opening 13 in the wooden bow member 1 and receivable in these openings is a tubular guide rod 14 which is removably fixed to the bow member 1 by means of a screw threaded,

, fastening device 15 which passes through the facing strip 3 and a nut 16 embedded. in the front face of the wooden bow-member 1, as clearly shown in detail in Fig. 4. The

a suitably fixed head 17 to limit the arching movement of the bow-gun member 1, and its facing strips, thereby preventing any undue bending of the bow members when arch? ing the same.

A suitable cross-head 18 having the finger recesses 19 is slidably mounted upon the guide rod 14 and is provided with ears 20 to which the inner ends of a pair of endless-bow cords 21 are suitably connected, the opposite or outer ends of the cords being suitably connected with the wire loop connections 7 which when at their normal inactive position are in contact with the rear face of the curved ends -of the bow members, as shown in Fig. 3, and with the guide rod 14 is provided at its rear end with rest and guide plate 25 provided with a suitable notch, or recess'26 for the arrow to rest upon, as clearly shown in Figs. 4, 6, 7 and 8 to afford a means for perfectalignment of the arrow.

The wooden bow member 1 is provided with a suitable front sight member 27 to the rear of the arrow rest and guide plate 25 and the slidably mounted cross head 18 is provided upon the socket member 23 with a suitably notched rear sight member 28, as clearly shown in Fig. 7, thereby affording -a means of acquiring efficiency in marksmanship equal to the same as provided in modern rifles. U v

In the modification shown in Fig. 9, I have eliminated the wooden bow member 1 and attached the two metallic bow member facing strips 3 and 8 together in any suit able manner, otherwise the construction is the same throughout, as will be apparent from the drawing.

From the foregoing description, it is evident that I provide a bow-gun having predetermined and uniform strength, that the bending or arching of the bow is limited and that I provide a device which permits the operator to accurately aim at objects at which he is shooting. It will also be observed that I provide a bow-gun which is substantially straight in its normal position and is only curved or arched when an arrow is to be projected thereby.

The many advantages of the herein described invention will readily suggest themselves to those skilled in the art to which it appertains. ,Li

I do not desire to be understood as limiting myself to the exact details of construction and arrangement of parts as herein described and illustrated, as it is manifest that variations and modifications may, be made without departing from the spirit and scope of my invention and the terms of the following claims, hence I wish it to be understood that I reserve the right to make any such changes, or modifications as may fairly fall within the scope of the appended claims when fairly construed.
